Dispensing device



Feb. 8, 1938. MELLEN DISPENSING DEVICE Filed June 17, 1935 QWUQ/YVM 51901 a Mel/e12 Patented Feb. 8, 1938 UNITED STATES DISPENSING DEVICE George Mellen, Diamond Head, Honolulu, Territory of Hawaii, assignor to H. 0. Hilts, Honolulu, Territory of Hawaii Application June 17, 1935, Serial No. 27,111

1 Claim. (01. 43-446) This invention relates to insecticide dispensers and the like, wherein the dispenser acts as a shipping container or package for the contents.

Heretofore, insect powders have been packed in containers which require that the powder be removed and placed in a spray gun or similar device, or simply poured from the receptacle. My invention provides that the powder may be forced from the package under pressure so that the powder will enter crevices, holes and the like, without the necessity of a separate apparatus.

The principal object of my invention resides in a package container which includes apparatus for forcing the contents of the package therefrom under pressure.

Another object is to provide a cheap, simple container which requires no charging and is ready for use by the operator so that the contents may be forced from the container under pressure Other objects of the invention will be disclosed in the specification and claims forming a part of this application.

In the drawing:

Figure 1 is a vertical section of the container showing the dispensing apparatus;

Figure 2 is a detailed perspective of a dispensing tube; and

Figure 3 is a horizontal section taken on the line 3-3 of Figure 1.

Referring to the drawing, in which similar parts are designated by like numerals:

Numeral i designates a cone-shaped container having flexible sides 5 of rubberized material, or the like, and a base member 6 of inverted U- shape in cross section made of a firm material, such as metal, containing a socket 1. The base member inserted-in the container 4, as illustrated in Figure 1, and having curled flanges 8, encircles the sides 5 to securely hold the base in place.

A tube 9 having staggered openings 10 and a conical-shaped shield II, is placed within the coneshaped container 4, the shield ll fitting into the top portion of the container, the sides thereof fitting snugly against the interior sides of the container 4, the top of the shield ll being below the discharge opening l2 of the container so as to form a chamber l3 between the shield II and the discharge opening l2. A partition 14 is placed in the lower end of the tube 9 to form a cup l5 to receive one end of a coil spring It, the other end of the spring resting in the socket 1, so as to normally keep the tube 9 in'extended position and return the sides 5 to an extended position after pressure has been exerted upon the same.

As actually constructed and used, the tube 9 will be placed in the container 4; that portion of the container surrounding the tube will be filled with an insect powder, or the ingredients to be discharged, and the spring IE will be placed in b the cup l5 and the base member inserted in the base of the container, the spring 16 fitting into the socket 1 and compressing the spring, the flanges 8 encircling the sides 5 to keep the base member in position. The container may then 10 be sold; and upon the purchaser using the same, he will place the discharge opening I! opposite the crack or opening through which the powder is to be discharged and by compressing the sides which are flexible, will force the powder through 15 the staggered openings I0, and in turn through the discharge opening 12, a bellows efiect being obtained. Upon the pressure being exerted upon the sides, the spring It will be further compressed, and upon the pressure being released, the spring 20 will force the base 6 into its original position and in turn straighten the sides 5. This operation may be repeated as material is desired to be discharged through the opening 12.

Numerous variations may doubtless be devised 25 by persons skilled in the art without departing from the principles of my invention. I, therefore, desire no limitations to be imposed on my invention, except such as are indicated in the appended 30 claim.

What I claim is: 1

A container comprising agfiexible conical wall having a discharge opening at one end, a solid closure member of frusto-conical form fitting into 35 the enlarged end of said conical wall, said closure member having a flange engaging the lower edge of said side wall and a flat transverse portion above the lower edge of said wall, a depression formed in said transverse portion extending sub- 40 stantially to the level of said lower edge and constituting a socket, a tube in alignment with the discharge opening of said container having its lower end fitting into said socket, and having apertures at intervals along its length, a cup 5 formed in the lower portion of said tube, and a resilient spring positioned in said cup and socket and normally under compression, said flexible Wall being adapted to force the contents of said container through the apertures in said tube, 50 and thence out through the discharge opening on the application of pressure to the wall and said spring being adapted to return the wall to its normal position.
